目的 研究柔性长摆臂对包装机械凸轮系统的影响， 为验证凸轮系统的设计是否满足要求提供一种直观的方法。方法 以糖果包装机械中常用的凸轮系统为研究对象， 通过SolidWorks建立凸轮系统三维模型， 通过Ansys建立柔性体的中性文件， 二者相结合创建刚柔耦合分析模型， 在ADAMS下对系统进行仿真， 获得相应实际位移输出曲线。结果 在考虑两摆臂为柔性体的情况下， 上下冲杆同步段之间的距离有一定的波动， 且最大变化为2~3 mm。结论 考虑到柔性体对凸轮系统的执行构件影响不大， 可在执行件上布置胶垫， 避免夹持中糖果被夹碎。

This work aimed to study the effects of the flexible long arm on packaging mechanical CAM system, in order to provide an intuitive way to test and verify whether the design of the CAM system could meet the requirements. Taking the CAM system widely used in candy packaging machine as the research object, after setting up the 3D model by SolidWorks, the MNF of the flexible body by Ansys, and the rigid-flexible coupling analysis model by combining these two, simulation of the system was conducted using ADAMS to obtain the corresponding actual displacement output curves. Considering the two swing arms as the flexible body, the distance between the upper and lower punch synchronization periods showed a certain fluctuation, and the biggest change was 2~3 mm. The effect of the flexible body on the actuator was not obvious, and the effect could be eased by setting some pieces of the rubber gasket on the actuator to avoid mincing of candy during holding.
